Dear Maintainer,
I use PulseAudio by starting it as a service:
---

[Unit]
Description=PulseAudio system server

[Service]
Type=notify
ExecStart=/usr/bin/pulseaudio --daemonize=no --system --realtime
--log-target=journal

[Install]
WantedBy=multi-user.target

---

but after updating the alsa-utils package from version 1.2.5-2 to
version 1.2.6-1, pulseaudio does not start and the status of the service
returns this error:

PulseAudio [1620]: Failed to Load Module "Module-Native-Protocol-Unix"
(Argument: ""): Initialization Failed.

I have compared the contents of the two packages and I noticed that the
services:

- alsa-state.service
- alsa-restore.service

have been moved from the path "/usr/lib/systemd/system" ->
"/lib/systemd/system" and this create the problem.

ln -sfn
/lib/systemd/system/{sound.target.wants,alsa-restore.service,alsa-state.service}
/usr/lib/systemd/system/

And this time, at reboot, everything worked.

I think it is necessary to create this symlinks in the post-installation
script to avoid interruptions of the audio system.

Thank you,
Antonio

I thought I solved it, but it wasn't the problem, the next reboot has
recurred.

However, after more than a reboot, the downgrade to the previous 1.2.5
version works.
